...apartment and this is happening. I have asked this question on here before and I have gotten several good answers. I moved so she is no longer in the same place. But I did place her by the window like I had her in my old home. Since I have moved I haven't gotten around to cleaning her cage. She is continuing to lay eggs. She is now up to 5. She hisses at me at night when I cover her up. There are no vets in my area that deal with birds. I haven't removed any of the eggs since the first time she had them and I was told not to remove them because she would continue to lay eggs and this would be bad for her. I have started buying her the tropical treats that you can get at wal-mart. Is there anything else I need to be doing? How soon should this stop? It has been going on for almost 2 months. She has had about 8 eggs in that time. Thanks for all of the help.
